Etoffer Autocad de figure 2D simple...

[bonuscad]

Je vous propose 3 routines pour créer des figure 2D simple (avec polyligne) .

 

Si ces figures sont simples le programme l'a été un peut moins. J'ai voulu sophistiquer le mode dynamique avec la fonction (grread) qui n'accepte pas le mode des ACCROBJ

la fonction (gr-osmode) ma permis de re-simuler ces mode d'accrochage. Tout commentaire sur ce code est le bienvenu.

C'est de l'émulation d'ACCROBJ ?...

 

J'avoue que j'ai du mal à comprendre,..le but....ce qui m'étonne aussi c'est que mes accrobj ont changé de couleurs, attends voir, je vais regarder comment ca se passe.....

 

Sinon, big applause, c'est du top, comme d'habitude.
